【０００２】[0002]
電子回路を熟知する者ならわかるように、インダクタ自身はローパスフィルタ になることができ、コンデンサを加えた場合、挿入損失（insertion loss）を 大きくし、ローパスフィルタの効果を増加することが出来る。 As those familiar with electronic circuits will know, the inductor itself can be a low-pass filter, and adding a capacitor can increase the insertion loss and increase the effect of the low-pass filter.
【０００３】 一般的に、現行のコンデンサと、インダクタと結合することによりなるローパ スフィルタの製造方法は実体を備えるコンデンサ（例えばセラミックコンデンサ など）の一端を２つのインダクタに直列して３つの端子を備えるローパスフィル タを構成する。図１Ａで示される公知のローパスフィルタは、セラミックコンデ ンサ１０と２つのインダクタ２０と３つの端子３１、３２、３３からなる。この ２つのインダクタ２０の電性はセラミックコンデンサ１０の一端に結合され、図 １Ｂで示されるような等価回路を構成する。明らかなように、この種の公知のロ ーパスフィルターのコストは高く、表面粘着素子ではないことがわかる。In general, a method of manufacturing a current capacitor and a low-pass filter by combining with an inductor includes a capacitor having a substance (for example, a ceramic capacitor) having one end connected in series with two inductors and three terminals connected thereto. A low-pass filter to be provided. The known low-pass filter shown in FIG. 1A includes a ceramic capacitor 10, two inductors 20, and three terminals 31, 32, and 33. The conductivity of the two inductors 20 is coupled to one end of the ceramic capacitor 10 to form an equivalent circuit as shown in FIG. 1B. As can be seen, the cost of this type of known low-pass filter is high and not a surface-adhesive element.
【０００４】 これにより、コストが低く、表面粘着素子であるローパスフィルタが望まれる 。Accordingly, a low-pass filter that is low in cost and is a surface adhesive element is desired.

More specifically, the first flat coil is formed by winding the first rectangular conductive flake several times, and after winding, each winding portion overlaps and has a first radius of the same length. Also, after winding the first rectangular conductive flake, the first upper surface is substantially parallel to the first lower surface. In addition, the first rectangular conductive flake becomes an inductor by being coated with an insulating material or a dielectric.
【０００８】 また、第二扁平コイルと第一扁平コイルは、類似又は同様の形状及び材質であ る。第二扁平コイルは断面が長方形で、第二上表面及び第二下表面を備える第二 長方形導電薄片が数回巻いて形成される。詳述すると、第二扁平コイルは第二長 方形導電薄片を数回巻くことにより構成され、巻いた後、各巻き部分は重畳して 、同じ長さの第二半径を備える。また、第二長方形導電薄片を巻いた後、第二上 表面は第二下表面にほぼ平行になる。この他、第二長方形導電薄片は絶縁物質ま たは誘電体により被覆される。本実施例において、第一半径と第２半径は同じで も異なっても構わない。The second flat coil and the first flat coil have similar or similar shapes and materials. The second flat coil has a rectangular cross section, and is formed by winding a second rectangular conductive flake having a second upper surface and a second lower surface several times. More specifically, the second flat coil is formed by winding the second rectangular conductive thin piece several times, and after winding, each winding portion overlaps and has a second radius of the same length. Also, after winding the second rectangular conductive flake, the second upper surface is substantially parallel to the second lower surface. In addition, the second rectangular conductive flake is coated with an insulating material or a dielectric. In this embodiment, the first radius and the second radius may be the same or different.
【０００９】 平板コンデンサの理論に基づくと、第一上表面と第二下表面は絶縁物質又は誘 電体によって被覆されるため、第一上表面と第二下表面との間は浮遊容量を形成 する。この時、第一上表面と第一下表面との間に電極板を挿入する場合、浮遊容 量は２つのコンデンサに分割される。本考案は第二扁平コイルにより、等価的に 複数の電極板を提供する。According to the theory of a flat plate capacitor, the first upper surface and the second lower surface are covered with an insulating material or a dielectric, so that a stray capacitance is formed between the first upper surface and the second lower surface. I do. At this time, when an electrode plate is inserted between the first upper surface and the first lower surface, the floating capacitance is divided into two capacitors. The present invention provides a plurality of electrode plates equivalently by the second flat coil.
【００１０】 本考案は２つの相隣する第一上表面と第一下表面との間に第二扁平コイルの一 巻きを挿入し、これにより、第二扁平コイルの第二上表面は第一下表面に面し、 且つ第二下表面は第一上表面に面する。本考案は第二扁平コイルの一端が接地す る。第一扁平コイル及び第二扁平コイルは数回巻かれた螺旋体であるゆえ、第一 扁平コイルと第二扁平コイルは互いに挿入されて、ローパスフィルタを形成する ことが出来る。[0010] The present invention inserts one turn of the second flat coil between two adjacent first upper surfaces and the first lower surface, whereby the second upper surface of the second flat coil becomes the first upper surface. Facing the lower surface, and the second lower surface facing the first upper surface. In the present invention, one end of the second flat coil is grounded.

【００１２】[0012]
上述した本考案の目的、特徴、及び長所をより一層明瞭にするため、以下に本 考案の好ましい実施の形態を挙げ、図を参照にしながらさらに詳しく説明する。 In order to clarify the purpose, features and advantages of the present invention described above, preferred embodiments of the present invention will be described below with reference to the drawings.
【００１３】 本考案のインダクタは実体を備えない浮遊容量により、挿入損失を増加してロ ーパスフィルタのフィルタ効果を向上する。本考案のフィルタは扁平の表面粘着 素子である。The inductor of the present invention increases the insertion loss and improves the filtering effect of the low-pass filter due to the stray capacitance having no substance.

【００１４】 図２Ａは本考案の一部分を示す図で、図２Ｂは第一扁平コイル１００の断面図 である。本考案は、コア構造３００及び２つの扁平コイルを備え、それぞれ第一 扁平コイル１００、第二扁平コイル２００とする。第一扁平コイル１００は断面 が長方形で、第一上表面１１０及び第一下表面１２０（図２Ｂの断面図で示され る）を備える第一長方形導電薄片が数回巻いて形成される。詳述すると、第一扁 平コイル１００は第一長方形導電薄片を数回巻くことにより構成され、巻いた後 、各巻き部分は重畳して、同じ長さの第一半径R１を備える。また、第一長方形 導電薄片を巻いた後、第一上表面１１０は第一下表面１２０とほぼ平行になる。 この他、第一長方形導電薄片は絶縁物質または誘電体（図示せず）により被覆さ れることにより、第一扁平コイル１００はインダクタになる。FIG. 2A is a view showing a part of the present invention, and FIG. 2B is a sectional view of the first flat coil 100. The present invention includes a core structure 300 and two flat coils, which are referred to as a first flat coil 100 and a second flat coil 200, respectively. The first flat coil 100 has a rectangular cross section and is formed by winding a first rectangular conductive flake having a first upper surface 110 and a first lower surface 120 (shown in a cross-sectional view in FIG. 2B) several times. More specifically, the first flat coil 100 is formed by winding a first rectangular conductive flake several times, and after winding, each winding portion overlaps and has a first radius R1 of the same length. Also, after winding the first rectangular conductive flake, the first upper surface 110 is substantially parallel to the first lower surface 120. In addition, the first rectangular conductive flake is coated with an insulating material or a dielectric (not shown), so that the first flat coil 100 becomes an inductor.
【００１５】 図２Ａを引き続き参照すると、第二扁平コイル２００と第一扁平コイル１００ は、類似又は同様の形状及び材質である。詳述すると、第二扁平コイル２００は 断面が長方形で、第二上表面２１０及び第二下表面２２０を備える第二長方形導 電薄片が数回巻いて形成される。詳述すると、第二扁平コイル２００は第二長方 形導電薄片を数回巻くことにより構成され、巻いた後、各巻き部分は重畳して、 同じ長さの第二半径R２を備える。また、第二長方形導電薄片が巻いた後、第二 上表面２１０は第二下表面２２０にほぼ平行になる。この他、第二長方形導電薄 片は絶縁物質または誘電体（図示せず）により被覆される。本実施例において、 第一半径Ｒ１と第２半径Ｒ２は同じでも異なっても構わない。With continuing reference to FIG. 2A, the second flat coil 200 and the first flat coil 100 are similar or similar in shape and material. More specifically, the second flat coil 200 has a rectangular cross section, and is formed by winding a second rectangular conductive strip having a second upper surface 210 and a second lower surface 220 several times. More specifically, the second flat coil 200 is configured by winding a second rectangular conductive thin piece several times, and after winding, each winding portion overlaps and has a second radius R2 of the same length. Also, after the second rectangular conductive flake is wound, the second upper surface 210 is substantially parallel to the second lower surface 220. In addition, the second rectangular conductive flake is covered with an insulating material or a dielectric (not shown). In this embodiment, the first radius R1 and the second radius R2 may be the same or different.
【００１６】 注目すべきことは、第一長方形導電薄片の厚さがｔで、巻き数がＮである場合 、第一扁平コイル１００の厚さ（高さ）は約ｔＮである。同様に、第二長方形導 電薄片２００の厚さがｔで、巻き数がＮである場合、第二扁平コイル２００の厚 さ（高さ）は約ｔＮである。しかし、図では各コイル間の間隔をはっきり表示す るため、各コイル間の距離は実際より誇張して記されている。It should be noted that when the thickness of the first rectangular conductive flake is t and the number of turns is N, the thickness (height) of the first flat coil 100 is about tN. Similarly, when the thickness of the second rectangular conductive strip 200 is t and the number of turns is N, the thickness (height) of the second flat coil 200 is about tN. However, in the figure, the distance between the coils is exaggerated in order to clearly show the distance between the coils.
【００１７】 図２Ｂを参照してわかるように、平板コンデンサの理論に基づくと、第一上表 面１１０と第一下表面１２０は絶縁物質又は誘電体によって被覆されるため、第 一上表面１１０と第一下表面１２０との間は浮遊容量Ｃｓを形成している。この 時、第一上表面１１０と第一下表面１２０との間に電極板を挿入する場合、浮遊 容量Ｃｓは２つのコンデンサＣに分割される。即ち、本考案は第二扁平コイル２ ００の各巻きにより、等価的に複数の電極板を提供する。As can be seen with reference to FIG. 2B, based on the theory of a plate capacitor, the first upper surface 110 and the first lower surface 120 are covered with an insulating material or a dielectric, so that the first upper surface 110 And the first lower surface 120 form a stray capacitance Cs. At this time, when an electrode plate is inserted between the first upper surface 110 and the first lower surface 120, the stray capacitance Cs is divided into two capacitors C. That is, the present invention provides a plurality of electrode plates equivalently by each winding of the second flat coil 200.
【００１８】 図３Ａ〜図３Ｃは、それぞれ、本考案のフィルターを示す図、本考案のフィル ターの回路を示す図、本考案の分解図である。図３Ａで示されるように、本考案 は２つの隣接する第一上表面１１０と第一下表面１２０がなす界面間に第二扁平 コイル２００の一巻きを挿入して、図３Ｃに示されるようなコイルの結合体１５ ０を形成する。例えば、第二扁平コイル２００の一端から第一扁平コイル１００ に沿って巻きを挿入していく。よって、第二扁平コイル２００の第二上表面２１ ０は第一下表面１２０に面し、第二下表面２２０は第一上表面１１０に面する。 本考案は第二扁平コイル２００の一端が接地して、図３Ａで示される回路図にな る。第一扁平コイル１００及び第二扁平コイル２００は互いに挿入することによ り、本考案のローパスフィルタインダクタになる。3A to 3C are a diagram illustrating a filter of the present invention, a diagram illustrating a circuit of the filter of the present invention, and an exploded view of the present invention, respectively. As shown in FIG. 3A, the present invention inserts a single turn of the second flat coil 200 between the interfaces formed by two adjacent first upper surfaces 110 and first lower surfaces 120, as shown in FIG. 3C. A coil combination 150 is formed. For example, winding is inserted from one end of the second flat coil 200 along the first flat coil 100. Therefore, the second upper surface 210 of the second flat coil 200 faces the first lower surface 120, and the second lower surface 220 faces the first upper surface 110. In the present invention, one end of the second flat coil 200 is grounded, resulting in the circuit diagram shown in FIG. 3A. The first flat coil 100 and the second flat coil 200 are inserted into each other to form the low-pass filter inductor of the present invention.
【００１９】 図３Ｃで示されるように、図３Ａの第一扁平コイル１００及び第二扁平コイル ２００を互いに挿入されて出来たコイル結合体１５０は、コア構造の中心に配置 する。コア構造は例えば（限定しない）コアベース３１０及びコアカバー３２０ を備える。コアベース３１０の外観は直方体で、底面と４つの側壁及び素子を収 納する凹槽３１５からなる。ある側壁は３つの開口３３０を備え、第一扁平コイ ル１００及び第二扁平コイル２００の末端を伸出し、伸出した末端が湾曲した後 、ローパスフィルタインダクタのピンにすることが出来る。その後、コアカバー ３２０はコイル結合体１５０を収納するコイルベース３１０上に結合し、本考案 のローパスフィルタインダクタが完成する。As shown in FIG. 3C, a coil assembly 150 formed by inserting the first flat coil 100 and the second flat coil 200 of FIG. 3A into each other is disposed at the center of the core structure. The core structure includes, for example (without limitation) a core base 310 and a core cover 320. The external appearance of the core base 310 is a rectangular parallelepiped, and includes a bottom surface, four side walls, and a concave tank 315 for storing the element. Certain sidewalls have three openings 330 that extend the ends of the first flat coil 100 and the second flat coil 200 and can be turned into pins for a low pass filter inductor after the extended ends are curved. Thereafter, the core cover 320 is connected to the coil base 310 that houses the coil assembly 150 to complete the low-pass filter inductor of the present invention.
【００２０】 図４を参照する。該図は“第一扁平コイル１００のみを備えるローパスフィル タインダクタ”と“第二扁平コイル２００を加えた後のローパスフィルタインダ クタ”（即ち、本考案のローパスフィルタインダクタ）の挿入損失と頻度の函数 図形とを比較するものである。曲線４００は第一扁平コイル１００の特性を示し 、曲線５００は第一扁平コイル１００に第二扁平コイル２００を加えた特性を示 すものである。見てわかるように、本考案は、第一扁平コイル１００のみをロー パスフィルタインダクタとする時に比べて、好ましい効果をもたらしており、そ れは、曲線５００は更に挿入損失が高いからである。Referring to FIG. The figure shows the insertion loss and frequency of the “low-pass filter inductor having only the first flat coil 100” and the “low-pass filter inductor after adding the second flat coil 200” (ie, the low-pass filter inductor of the present invention). It compares with a function figure. A curve 400 shows the characteristics of the first flat coil 100, and a curve 500 shows the characteristics of the first flat coil 100 plus the second flat coil 200. As can be seen, the present invention has a more favorable effect than when only the first flat coil 100 is used as a low-pass filter inductor, because the curve 500 has a higher insertion loss.
【００２１】[0021]
本考案は浮遊容量により、ローパスフィルタインダクタの挿入損失を増加して フィルタ効果を増進する。よって、実体のセラミックコンデンサ或いはその他の 形式的なコンデンサは別途に必要ないので、コストを低減することが出来る。こ の他、本考案は扁平コイルを使用するため、インダクタ全体も扁平形であると共 に、本考案のフィルタインダクタのピンは扁平形であるため、表面粘着素子にす ることが出来る。更に注目すべきことは、本考案は２つの導電体間の浮遊容量を 利用することを精神とする故、一般に良く見られる形状のコイル、例えば断面が 円形のコイルを用いても良い。 According to the present invention, the stray capacitance increases the insertion loss of the low-pass filter inductor, thereby enhancing the filtering effect. Therefore, the cost can be reduced because a real ceramic capacitor or other formal capacitors are not separately required. In addition, since the present invention uses a flat coil, the whole inductor is flat and the pins of the filter inductor of the present invention are flat, so that they can be used as surface-adhesive elements. It should be further noted that the present invention is based on the idea of utilizing the stray capacitance between two conductors, so that a coil having a commonly-used shape, for example, a coil having a circular cross section may be used.
